Figure A illustrates use of the on–chip level converter detailed in Figures 2 The 0 ~ 5 V Digital Control

signal is used to directly control a 9 Vp–p analog signal

The digital control logic levels are determined by VDD and VSS The VDD voltage is the logic high voltage; the VSS

voltage is logic low For the example, VDD = + 5 V = logic high at the control inputs; VSS = GND = 0 V = logic low The maximum analog signal level is determined by VDD and VEE The VDD voltage determines the maximum recommended peak above VSS The VEE voltage determines the maximum swing below VSS For the example, VDD –

VSS = 5 V maximum swing above VSS; VSS – VEE = 5 V maximum swing below VSS The example shows a ± 4.5 V signal which allows a 1/2 volt margin at each peak If voltage transients above VDD and/or below VEE are anticipated

on the analog channels, external diodes (Dx) are recommended as shown in Figure B These diodes should be small signal types able to absorb the maximum anticipated current surges during clipping

The absolute maximum potential difference between VDD and VEE is 18.0 V Most parameters are specified up to

15 V which is the recommended maximum difference between VDD and VEE

Balanced supplies are not required However, VSS must be greater than or equal to VEE For example, VDD = + 10

V, VSS = + 5 V, and VEE – 3 V is acceptable See the Table below
